As discussed in [1] it would be useful to have FSLASTBLOCK tag (size of the area occupied by filesystem). These few patches: - add interface to set FSLASTBLOCK - implement FSLASTBLOCK for ext2/3/4/jbd, xfs and btrfs - add BTRFS image for blkid test - update expected output for blkid tests to check FSLASTBLOCK The BTRFS image is default 'mkfs.btrfs btrfs.img' (115M in size; looks to be minimum required size) [1]: https://bugzilla.redhat.com/show_bug.cgi?id=2064810 Andrey Albershteyn (4): libblkid: add FSLASTBLOCK field interface showing area occupied by fs libblkid: add FSLASTBLOCK implementation for xfs, ext and btrfs blkid: add image for btrfs testing blkid: add tests for FSLASTBLOCK tag libblkid/samples/superblocks.c | 3 ++- libblkid/src/blkid.h.in | 23 ++++++++++++----------- libblkid/src/superblocks/btrfs.c | 5 +++++ libblkid/src/superblocks/ext.c | 5 +++++ libblkid/src/superblocks/superblocks.c | 13 +++++++++++++ libblkid/src/superblocks/superblocks.h | 1 + libblkid/src/superblocks/xfs.c | 1 + misc-utils/blkid.c | 2 +- tests/expected/blkid/low-probe-btrfs | 8 ++++++++ tests/expected/blkid/low-probe-ext2 | 1 + tests/expected/blkid/low-probe-ext3 | 1 + tests/expected/blkid/low-probe-jbd | 1 + tests/expected/blkid/low-probe-xfs | 1 + tests/expected/blkid/low-probe-xfs-v5 | 1 + tests/ts/blkid/images-fs/btrfs.img | Bin 0 -> 120586240 bytes 15 files changed, 53 insertions(+), 13 deletions(-) create mode 100644 tests/expected/blkid/low-probe-btrfs create mode 100644 tests/ts/blkid/images-fs/btrfs.img -- 2.27.0
